CRIMPED YARN, METHOD FOR MANUFACTURE THEREOF, AND FIBER STRUCTURE

摘要

Disclosed are: a crimped yarn which comprises a synthetic fiber comprising an aliphatic polyester resin (A) and a thermoplastic polyamide resin (B) and in which the ratio of the exposed surface area of the aliphatic polyester resin (A) to the surface area of the fiber is 5% or less, wherein a multifilament composed of a plurality of the synthetic fibers is crimpled; a fiber structure comprising the crimped yarn as at least a part of the fiber structure. More specifically, disclosed are: a crimped yarn which comprises a polymer alloy synthetic fiber comprising an aliphatic polyester resin (A) and a thermoplastic polyamide resin (B); a crimped yarn which comprises a core-sheath-type composite fiber, wherein the core component comprises an aliphatic polyester resin (A) or a polymer alloy composed of the aliphatic polyester resin (A) and a thermoplastic polyamide resin (B) and the sheath component comprises the thermoplastic polyamide resin (B); and a fiber structure comprising the crimped yarn as at least a part of the fiber structure.
